Here, if it is determined that H ≧ H ₀ + α, the power supply to the electric heater 12 is stopped in step S8, or O
N / OFF control is performed, the humidifying operation is stopped, or the amount of humidification is reduced.

As described above, when the good morning operation mode is set, when a predetermined time (for example, 4 hours) elapses after the good morning operation mode is set (for example, coldness becomes severe as in early morning in winter). Moreover, since the humidification operation is started when the decrease in humidity is large), the sensible temperature can be softened by the room temperature rise due to the humidification operation, and the indoor air can be prevented from drying. Moreover,
After the start of the humidifying operation, the detected humidity H rises by a constant value α (for example, 10%) from the initial humidity H ₀ , the sensible temperature is softened, and the dry state is avoided. Thus, it is possible to obtain a comfortable wakeup while saving power consumption. In addition, the humidifying operation is suitable for infants.

(IX) Automatic Humidification Operation IX (Refer to Flowchart in FIG. 12) In step S1, a specific operation mode (for example, good morning operation mode) is set (that is, the good morning operation mode is selected by the operation changeover key 44). If it is determined that the t ₁ timer (for example,
(4 hour timer) is started, and when it is determined in step S3 that the t ₁ timer has counted up (that is, time t ₁ has elapsed), the initial room temperature Tr ₀ is stored in the microcomputer 56 in step S4, and the step The detected room temperature Tr detected by the room temperature sensor 62 is input to the microcomputer 56 in S5, the electric heater 12 is energized in step S6, and the humidifying operation is started.

Then, at step S7, the detected room temperature T

As described above, when the good morning operation mode is set, when a predetermined time (for example, 4 hours) elapses after the good morning operation mode is set (for example, coldness becomes severe as in early morning in winter). Moreover, since the humidification operation is started when the decrease in humidity is large), the sensible temperature can be softened by the room temperature rise due to the humidification operation, and the indoor air can be prevented from drying. Moreover,
After the start of the humidifying operation, the detected room temperature Tr rises by a constant value β (for example, 3 ° C.) from the initial room temperature Tr ₀ , the sensible temperature is moderated, and the dry state is avoided. Thus, it is possible to obtain a comfortable wakeup while saving power consumption.

(X) Automatic Humidification Operation X (Refer to Flowchart in FIG. 13) In this case, the humidifier is provided with a clock function, and a specific operation mode (for example, good morning operation mode) is set in step S1. If it is determined that the good morning operation mode has been selected by the operation switching key 44, if the time is determined to be 3:00 am in step S2, the electric heater 12 is energized in step S3, and the humidifying operation is performed. Is started.

When it is determined that the time is 6:00 am in step S4, the energization of the electric heater 12 is ON / OFF controlled in step S5, and the humidification amount is reduced.

As described above, when the good morning operation mode is set, the humidifying operation is started at 3:00 am (for example, when it is severely cooled and the humidity is greatly reduced like in the early morning of winter). In addition, the sensible temperature can be softened by increasing the room temperature by the humidifying operation, and the indoor air can be prevented from drying. Moreover, after the start of the humidifying operation, at 6 am, when the sensible temperature is softened and the dry state is avoided, the humidifying operation is stopped or the humidifying amount is reduced, so that the power consumption is saved. You can get a comfortable wake up.

(XI) Automatic Humidification Operation XI (Refer to the Flowchart shown in FIG. 14) In this case, the humidifier is provided with a clock function, and a specific operation mode (for example, asthma operation mode) is set in step S1. If it is determined that the asthma operation mode has been selected by the operation switching key 44, the initial room temperature Tr ₀ is stored in the microcomputer 56 in step S2, and the detected room temperature Tr from the room temperature sensor 62 is stored in the microcomputer 56 in step S3. Entered in
In step S4, ON / OFF control of the electric heater 12 is started, and the humidifying operation with a small humidification amount is started.

Then, at step S5, the detected room temperature T
r is compared with a value (= Tr ₀ −γ) obtained by subtracting a predetermined constant value γ (for example, 10 ° C.) from the initial room temperature Tr ₀ , where Tr ≧ Tr ₀ −γ is determined. Then, in step S6, the electric heater 12 is continuously energized, and the humidifying operation with a large humidification amount is started.

The humidifying operation with the large humidification amount is performed in step S
7 continues until the time is determined to be 6:00 am in step 7, but if an affirmative determination is made in step S7, the ON / OFF control of the electric heater 12 is started in step S8, and the humidifying operation with a small humidification amount is started. It

As described above, when the asthma operation mode is set, until the room temperature Tr drops in the morning,
Humidification operation is performed with a small amount of humidification, and the room temperature Tr is the initial room temperature T.
When the value decreases from r ₀ by a constant value γ, the humidification operation is switched to the large humidification amount. Therefore, it is possible to obtain the required amount of humidification in a required time period while suppressing the power consumption.

(XII) Automatic humidification operation XII (Fig. 15)
In this case, the electric power supplied to the electric heater 12 is variable, and it is determined in step S1 that the operation mode is weak (that is, the weak operation mode is selected by the operation switching key 44). In step S2, energization of the electric heater 12 with high power is started, and in step S3, the detected water temperature Tw from the water temperature sensor 64 is input to the microcomputer 56. The heating with the high electric power is continued until it is determined in step S4 that the detected water temperature Tw reaches the temperature Td at which steam is generated. In step S4, Tw ≧.
When it is determined to be Td, the electric heater 12 is started to be energized with low power. By doing so, even in the humidifying operation in the weak operation mode, heating is performed with high electric power until steam is generated, and the time until steam generation can be shortened. The generation of steam may be detected by the steam temperature Ts detected by the steam temperature sensor 65.

(XIII) Automatic Humidification Operation XIII (Refer to the Flowchart shown in FIG. 16) In this case, a low temperature humidification mode is additionally provided as an operation mode, and if it is determined in step S1 that the low temperature humidification mode has been set, step S2 At, the detected steam temperature Ts from the steam temperature sensor 65 is input to the microcomputer 56, and the detected steam temperature Ts is compared with the reference temperature of 60 ° C. in step S3. Where Ts <
When it is determined that the temperature is 60 ° C., the process proceeds to step S4, and the electric heater 12 is energized. However, when it is determined that Ts ≧ 60 ° C., the process proceeds to step S5, the power supply to the electric heater 12 is stopped, and the humidifying operation is performed. Is stopped. In this way, humidification operation with low temperature steam becomes possible, and energy saving humidification is obtained.

By the way, an infant mode may be provided as the specific operation mode.
